Well, I'm snowed under with assignments, and I stupidly chose to do a flash animation for one of them >< so I did this as a preliminary to it.
If you didn't know, the Battle of Milvian Bridge was where the emperor Constantine the Great had his vision of a cross and a voice telling him that victory was assured if he bore the sign of the cross. He did, and defeated his rival Maxentius.
However, this is how it most likely went.
First animation I've done that syncs to music, apart from a scrapped project using The Real McKenzie's song Nessie.
